2 Claims. (Cl. 160-102) This invention relates to safety window grills or bars for windows in homes, to serve the purpose of preventing small children from toppling through an open window.

The main object of the invention is the provision of a new and improved construction whereby the grill bars are automatically raised or extended to obstruct the window as the sash is raised and which are automatically lowered with lowering of the sash, so that no matter how much or how little the sash is raised the window opening will always be obstructed by the bars.

Another object of the invention is the provision of a plurality of vertically extensible and collapsible grill bars secured by their lower ends to the window frame or sill and by their upper ends to the window sash, whereby the bars are automatically extended or collapsed as the sash is raised or lowered.

Still another object is the provision of the safety window grill mentioned above, which is simple and inexpensive of construction and installation, and which requires no attention on the part of the householder during its long life, and which will always function in the manner mentioned above.

The above broad as well as additional objects will be clarified in the following description wherein reference numerals refer to like-numbered parts in the accompanying drawing. It is to be noted that the drawing is intended solely for the purpose of illustration and that it is therefore neither desired nor intended to limit the invention necessarily to any or all of the exact details of construction shown except insofar as they may be deemed essential to the invention.

Referring briefly to the drawing, Fig. 1 is a front elevational view of a slide window equipped with a safety window grill embodying the features of the present invention, showing the bottom sash raised.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary front elevational view of the window, showing the bottom sash lowered or closed.

Fig. 4 is a sectional view taken on the line 4--4 of Fig. 2.

Referring in detail to the drawing, the numeral indicates the frame of a standard double-hung slide window, having slidable therein the upper or outer sash 11 and the lower or inner sash 12. As is common, the window is normally opened by raising the lower sash 12, and with the window thus open at the bottom it presents a danger to small children who may crawl through it on the sill, or who may otherwise be endangered by the open space in that they may fall through it.

Stationary grills, fixed to the window frame or the house wall adjacent thereto, have been provided to overcome this danger. However, such a permanent grill is an obstruction to vision when the window is closed, as it is in cold weather. The present invention obviates this defect. Further, removable grills are known, which the householder must insert manually after raising the lower sash. This involves not only a repeated nuisance, but

- 2 also the possibility of forgetfulness or delay in leaving the opening unobstructed for a time owing to an interruption just after raising the sash, during which time the open window offers the same danger. The present invention also obviates these defects.

In the embodiment of the invention illustrated in the drawing a horizontal bracket 13 is attached to the lower rail 14 of the sash 12, and, in the same vertical plane therewith, a second horizontal bracket 15 is secured to the wall of the sill 16. The bracket 15 is provided with spaced loops, sockets, or the like 17.

The bracket 13 is provided with upright extensions 18, equal in number and similar in spacing, to the sockets 17. Each bracket arm 18 has a horizontal extremity 19 provided with an opening for the passage therethrough of a screw or the like 20. The screws 20 are respectively in vertical alignment with the sockets 17.

For each pair of vertically aligned sockets 17 and screws 20, a telescopic rod 21 is provided. The lowermost section 22 of each rod is firmly anchored, by any suitable means or in any suitable manner, in its socket 17, and the uppermost section 23 is provided with an axial opening, not shown, in which the screw 20 registers after passing through the opening, not shown, in the arm extremity 19 which, it is to be noted, extends substantially at right angles to the plane of the arm and the bracket 13. Thus, with both the top section 23 and the bottom section 22 firmly anchored, the rods 21 will be extended or elongated automatically as the sash is raised, and will be collapsed or shortened automatically as the sash is lowered. As a result, the open space between the sash and the sill will at all times be obstructed by the grill formed by the rods 21, so that a small child or infant will be unable to get through the window opening.

Obviously, modifications in form or structure may be made without departing from the spirit or scope of the invention. 1

I claim:

1. In combination with the vertical side wall of a sill and the bottom sash of a slide window, a horizontal bracket secured to said sill wall and having a number of horizontally spaced sockets therein, the same number of similarly spaced arms secured to the sash, each of said arms having a horizontal extension outward from said sash in vertical alignment with one of said sockets, the same number of vertical telescopic rods having bottom end sections and top end sections, each of said bottom end sections being rigid in one of said sockets, and means for securing said top end sections rigidly in said extensions.

2. In combination with the vertical outside wall of a sill and the bottom sash of a slide window, a horizontal bracket secured to said sill wall and having a number of spaced sockets thereon having the axes thereof vertical, a horizontal bracket secured to the vertical outside wall of the bottom rail of said sash and having said number of similarly spaced arms extending upward therefrom substantially above the level of said rail, each of said arms having a horizontal right-angle extension from the upper end thereof provided with a screw receiving opening therein in vertical alignment with one of said sockets, the same number of vertical telescopic rods having a bottom end section and a top end section, each of said rods being mounted between one of said sockets and that one of said extensions having said screw receiving opening in alignment therewith, the bottom end sections being rigid in said sockets, the top end sections having threaded openings therein, and a screw passing through each of said screw-receiving openings and the threaded opening of the aligned top end section, said rods thereby being secured at their top and bottom ends and adapted 3 to be extended or collapsed accordingly as the sash is raised or lowered, the height of said arms being substantially equal to the length of said rods in fully collapsed position.
